shapes3dShapes: 3D shapes plot

Description Usage Arguments Value References See Also Examples

Description

This function is a slight modification of the original shapes3d function of the shapes R package so that the resulting plot has customized title and axes. Specifically, the changing lines regarding the original function are those related to its argument axes3 when it is fixed to TRUE.

shapes3dShapes(x,loop=0,type="p",color=2,joinline=c(1:1),
               axes3=FALSE,rglopen=TRUE,main=main)

Arguments

x

See shapes3d.

loop
